THREAD-BOARD CLEANER non sPINNI'NG-MAoHINEs.

ard spinning frame and made with the least possible number of working parts and one which will be easily protected and kept clean. i I i Y According to my invention, I propose to reciprocate the-cleaner board mechanically lengthwise of the thread board by means located in the slotted tube which will extend lengthwise ofthethread board and above the same, the operating mechanism thus" being in greatpart protected from the collection of lint and waste by being inclosed in the slotted tube. 2 p H The particular mechanism which I prefer to use for reciprocating the cleaner board is an endless cord used'in connection with a traveler which is attachedfirst on oneside and then on 'theiother side'of: the cordto produce the reciprocation of the cleaner board.

Other features of my invention are hereinafter set forthand claimed. I i

The invention consists essentially. of the combination and arrangement of parts hereinafter set forth fand claimed.

felt or other like material 9 suitable for collecting the waste fiber which accumulates atthis point and which tends to get into the yarn as the latteris spun.

' Inorder to be turned back out of theway.

when the thread board is turned back in dolling, the cleaner is'hinged to a vertical back piece g by hinges g Means are provided for automatically moving the cleaner'board back andv forth lengthwise of the thread board from end to end and for housing and protecting the reciprocating mechanism and for this purpose I make use of anendless cord cl having means by which first'one side and then the other side of the cord is alternately attached to the cleaner board, the attachment being shifted at the end .of the traverse to give areciprocating movement. to the cleaner board without reversing the motion of-the endless cord, the cordbeing inclosed finaslo'tted tube whereby it is thoroughly The cord (1 passes over idle pulleys e and e set at each end of the frame and it makes several turns around a driving pulley 6 made with a slight taper to prevent riding or kinking of the cord.

As here shown, I make use of a slotted tube f'to house the cord and to keep it from collecting lint etc. This tube is mounted on supports f so that it is held above the thread board and parallel therewith. The

tube has a slot 3 which extends throughout its entire length and at the extreme end thereiis an additionalslot or enlargement f 2 formed for the purpose hereinafter set forth.

' ,Connection is made between the cleaner board and the cord as here shown by means of a traveler H which is generally cylindrical jlII fOI'IIL tO fit the inside .of the tube f'and is -adapt'ed'to slide therein. i I

he. cleaner board is The connection with made by means of a double wire hook h which is secured. by one endto the traveler and extends outthrough the groove f bending downward andupward to. enter a vertical opening g in the head 9 which is formed on i the upper end ofthe'uprights g, the latter being secured to the back piece g.

The-cleaner board may end to end by a stop or enlargement cl secured on the cord at any point. This stop maybe a metal sphereor bullet perforated to "admitthe passage of the cord and upset thus be connected or disconnected from the traveler by hooking" or unhooking it from the hook .h. The 3 traveler is propelled through the tube from' to hold it in place. Two parallel passages or openings are formed in the traveler ex tending from end to end to admit the passage of the two sides of the endless cord. These passages are so arranged that the stop will be caught and held in one side until the end'of the traverse is reached when it will be allowed to escape and pass around the pulleysto enter the opposite side and be there caught. This is accomplished, by forming a shallow groove h in each side of the traveler, one on each end, this groove being just large enough to allow the cord to pass when confined by the walls of the tube but it is not large enough to permit the passage of the stop (1. At the inner end of each groove there is a lateral enlargement 71. in the traveler to make room for the stop and from there to the opposite end is a passage 7L2 large enough to allow the stop to pass. Thus, considering Figs. 5 and 6 assuming that the cord is moving as shown by the arrows, the stop has been drawn through the opening k and has there lodged in the recess h' as it could not pass through the groove 71/ on account of the proximity of the Wall of the tube. The traveler is thus drawn along to the right and is shown in Fig. 6 as just approaching the end of the tube and the lateral opening f in the end of the tube. As soon as the groove 7r opens into the space f where it is no longer closed by the walls of the tube, the stop d is released and slips from the recess it so that the cord no longer propels the traveler and the latter is prevented from being drawn out of the tube by any possible friction with the cord by a stud or screw f 5 in the tube. The stop 01 having been released from one side of the traveler, it passes around the pulley or pulleys and returns to the traveler, moving in the opposite direction and entering the traveler through the other opening, continuing through the large opening until it reaches the recess 72. on the opposite side where it is confined by the walls of the tube as before explainedand starts the traveler in the opposite direction. When the opposite end of the tube is reached this operation'is repeated, the opening f being so located at each end as to release the stop at the desired point. Thus the traveler is-reciprocated back and forth along the thread board by the action of the endless cord without any reversing mechanism applied to the cord.

The idle pulleys are attached to the machine by simple standards or brackets easily placed and the driving pulley is located on the continuation of one of the roller journals so that the whole operating mechanism may be easily attached to any standard spinning frame Without rebuilding it and with very few and simple changes.

The cleaner board may be lifted off and put back at any time by simply unhooking it from the traveler and when the thread board is tilted back the cleaner board goes with it.

It is evident that the endless cord may he used without the protecting tube and that other means than here shown maybe used for connecting first one side and then the other of the cord with the cleaner board.

I have shown the slot f as located above the middle and on one side but it may be otherwise located as desired.

The same means herein shown for reciprocating the thread board may be employed for reciprocating any other mechanical ele ment to which this motion is to he applied. The mechanism is simple and requires no complete reversing mechanism.

It is evident that other means than the endless cord may he used in the slotted tube for reciprocating the cleaner board.
